SPECIFICATION forming part of Letters Patent No. 629,727, dated July 25, 1899.

Application filed March 11, 18961 To all whom it may concern.-

Be it known that 1, WILLIAM H. TRAPHA- GEN, a citizen of the UnitedStates, residing at Rockford, in the county of lVinnebago and State ofIllinois, have invented certain new and useful Improvements inCultivators, of which the following isa specification.

The object of this invention is to form an attachment between theshovels and dragbar of a cultivator so that the shovels can be arrangedin what is known as open order and echelon.

In the accompanying drawings, Figure 1 is an isometrical representationof a cultivator drag-bar and the shovels arranged in open order. Fig. 2is a similar representation showing the shovels arranged in echelon.Fig. 3 is an enlarged representation of one of the brace-bars and aportion of the drag-bar. Fig. 4 is an isometrical representation of theshovel-standard bracket. Fig. 5 is an isometrical representation of thecap strengthening the shovel standard against lateral strain. Fig. 6 isan isometrical representation of the upper portion of theshovel-standard.

The drag-bar represented in the drawings consists of two parallel bars1, held separated by tubular blocks 2, having their front endsconverging and connected to a yoke 3, forming a part of the couplingbetween the dragbar and main frame of the cultivator. To the outer facesof the bars 1 are located bracebars, bent to form parallel portions 4and a diagonal portion 5. Each of the parallel portions is provided witha transverse opening 6. A bolt 7 passes through the drag-bar, tubularblocks, and the horizontal portions of the brace-bars lying in contactwith the outer faces of the parallel bars of the drag-bar. A bolt 8connects the horizontal portion of the brace-bar with the drag-bar. Abushing 9 is located upon the bolt and serves to support that end of thebrace-bar and hold it the required distance from the drag-bar.

Upon the outer face of each horizontal portion of the brace-bar islocated a bracket 10, having a central perforation 11 to receive itsbolt and has flanges embracing the upper and lower edges of thebrace-bar and has vertical ribs 12. Between these Vertical ribs is 10-Serial No. 582,762. (No model.)

cated a shovel-standard 13, of rectangular bar form and having anopening to receive the bolt. A cap 14 is placed upon the bolt and hasvertical ribs embracing the vertical edges of the shovel-standard, and anut placed upon the bolt serves to clamp the shovel-standard and thedrag-bar together. By.means of the brace-bars the location of theshovelstandard can be changed to set the standards nearer or fartherfrom the drag-bar by reversing the brace-bar end for end, transferringthe bolts and bushings to correspond, and when the second shovel fromthe forward end of the drag-bar is farther from the drag-bar than thefirst shovel their position is said to be open order, as shown at Fig.1, and when set as shown at Fig. 2 they are said to be in echelon.

It will be noticed that the attachments of all the shovel-standards arethe same,with the exception of the third standard from the front, itbeing located on the outside of the drag bar. The cap of this standardhas a central de pression of a size to receive the head of the boltconnecting it with the drag-bar, and the outer edges of this cap arerounded. The lo cation of this standard with respect to thecarrying-wheels of the cultivator is such that in swinging the drag-barduring the process of cultivation the attachment of the standard withthe drag-bar will engage the wheel and some part of the structure bebroken, but by making the cap smooth and allowing the countersinking ofthe holding-bolt this obj ection is removed. This cap can be used on allthe standards without detracting from the merits of the invention.

The handle 15 takes the place of the tubu lar block of the rearstandard, and a bracerod 16 holds it at the proper angle.

The shovels 17 have a connection with their standards in any suitablemanner.

I claim as my invention- 1. In a cultivator the combination of a dragbar, two shovel-standards, a brace-bar connecting the standards havingtwo parallel portions and a diagonal portion, the parallel portionsconnected with the standards in order that it may be made changeable endfor end.

2. In a cultivator the combination of a drag- I order that the cap orhead of the bolt will not bar, shovel standards secured thereto byengage the Wheel.
